Residents and Revolutionary Grid Control Find Home in Rural Renewable Energy District (Text Version)

NREL's algorithms for autonomous energy grids make real-world debut in Basalt Vista, a net-zero development in rural Colorado. As the project scales up—from a few homes, to a few dozen—NREL's autonomous energy grids could be the solution to realizing highly renewable energy systems.

Video opens with an aerial shot of the Basalt Vista development, which is under construction.

We are here on-site at Basalt Vista in Basalt, Colorado, which is a Net-Zero affordable housing community built for our teachers and our county workers to live in.

Basalt is near Aspen and Snowmass…It's a fairly wealthy resort community.

Bryan Hannegan, President & CEO of Holy Cross Energy appears on-screen.

These teachers make $50,000-$55,000 a year.

There's no way they can afford to own a home in this area. Our kids deserve great teachers and this is a way to recruit them and keep them here.

It came out of this idea of how to build a house that's also a microgrid.

It's easy to build a cheap home. It's hard to build an efficient home, not efficient only to buy, but efficient to live in. Maybe the best approach is to build homes

producing as much energy it's consuming,

to know when to use power and when not to use power, or have the ability to put storage inside your house, it really flips the switch

on how those electrical lines are used.

Holy Cross Energy was very unique in that it deployed advanced metering infrastructure very early on.

In 2015, we did a full rollout and at that point, we started gathering data. Unless you have the talent in-house to figure out what to do with the data,

it's just data, sitting on a server.

Our hope with Basalt Vista was to understand how distributed energy resources will become a part of our energy system going forward,

but no utility really likes to experiment with its customers.

NREL was chosen for this project because of the unique capabilities, the Energy Systems Integration Facility, a little distribution grid in a box, if you will.

It helps us develop and test the tools that we're gonna need, the algorithms, the controls model and simulate advanced grids with distributed resources connected to them.

It gave us confidence that what we saw in the laboratory, we would actually see in the field

and that took all the risk out of the equation for us, which is important for utilities when they're doing R&D.

The key piece of technology NREL's bringing to this project is the software portion,

the algorithm that integrates it all together and optimizes how all these different resources are balanced.

Testing is done in computer-only simulations,

is putting that as close to the real world as you possibly can before actually putting it into a customer's home.

to fully validate the technology. NREL has already proved that this technology can be applied to millions of homes

can be also applied to other cooperatives and utilities. 

Chris Bilby on a conference call: Can we do this with a load controller? 

[on the phone] Yes, that can minimize the impact.

Holy Cross has an ambitious goal of the renewable energy integration in their system.

This will provide a national example and also, provide a national impact for the other utility companies.

For us, it was to build a community that was resilient and reliable and self-sustaining, but really, where NREL came into play

was they were able to take that model

and scale it and then run that in their simulation of what would it look like if we had 160 Basalt Vistas out there, and then let's see what grid impacts we would have in a year.

When you have a laboratory like NREL has,

it doesn't take you a year to do that analysis; you can do that analysis in three or four days.

This is about energy system design

It's about creating clean energy at a pace and a scale that matters.

gonna be part of the trend of the future. Others are beginning to say, "Well, how can we do this, too?"

I think it's a real pleasure and an honor to be able to put one of the first stakes in the ground and say, "Yeah, you know what, this can be done and maybe we should do more of it."

and to be a part of something so grand, it just helps me be more true to what I teach.
